Probably yes, but never stop paying attention. I would count on a person with a lot of positive feedbacks as it is probably not a bought account. Plus, such a person does not want to be associated with shady projects (mistakes are made, but make it more times and your hard-earned respect from the community is turned to dust). In general, I would trust them more than some newbie-like looking accounts with no history. It looks like they have put some effort into looking more legitimate, which is precious in this field.
